A new alternative in the manufacture of this material are construction waste class A as aggregates, this way can lead to a reduction of discarded materials, reducing environmental impacts. It is also necessary to highlight the need for analysis in situationsde incêndios, visando definir o estado da estrutura após ser exposta ao fogo. In this sense, this paper addresses the study in fire situation of concretes produced with civil construction waste class A. For this, a mix was defined by replacing 50% of the gravel by CCR as coarse aggregate, and its properties were analyzed at certain temperatures. In general, the analyzed concrete did not show good behavior compared to conventional concrete.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786203382389\"\u003e\u003ch3\u003ePHYSICAL AND MECHANICAL PROPERTIES OF CONCRETE PRODUCED FROM CONSTRUCTION WASTE IN FIRE SITUATION\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786203382389","offer_id":40148994654301,"sku":"9786203382389","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5b5e45b7-488f-42c6-b29e-7fb6293dbad4.jpg?v=1757569733","url":"https:\/\/shop.autorenwelt.de\/en\/products\/concrete-analysis-von-beatriz-verssao-spirandio","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
